Observation of the Decay B 0 s → ψ(2S) φ and a Measurement of B(B 0 s → ψ(2S) φ)/B(B 0 s → J/ψ φ) with the DØ detector * The DØ Collaboration We report in this note the observation of the decay B 0 s → ψ(2S) φ using about 300 pb −1 of Run II data collected with the DØ detector at Tevatron. Using the decay B 0 s → J/ψ φ as normalization we report a… (More)
